Hepatitis B How Is It Spread

How To Help Stop The Spread Of Hepatitis B

Can Hepatitis B spread through food? | Apollo Hospitals

There are several things you can do to help stop the spread of this disease. Please follow these instructions until your doctor tells you the child with hepatitis is completely well:

  • Good hand washing by all family members must be done. Hands should be washed using soap and warm water before meals, after using the bathroom and before preparing or serving food.
  • Wash your hands after caring for your child. You may have come in contact with the hepatitis B virus from such things as changing diapers, cleaning up vomit, or exposure to blood.
  • Wear disposable gloves when handling blood . Wash your hands after removing the gloves.
  • Hepatitis B can be spread by sexual activity. Not having sex is the best way to keep Hepatitis B from being spread sexually. If an infected person has sex, a condom should be used every time. Condoms should be used until the doctor says there is no longer any risk of spreading the disease.
  • All family members who are not infected should get Hepatitis B vaccines .

Reduce Your Chance Of Infection

You can reduce your chance of hepatitis B infection by

  • not sharing drug needles or other drug materials
  • wearing gloves if you have to touch another persons blood or open sores
  • making sure your tattoo artist or body piercer uses sterile tools
  • not sharing personal items, such as toothbrushes, razors, or nail clippers
  • using a latex or polyurethane condom during sex

Return To School Or Child Care

  • Your child may return to normal daily activity when the childs doctor or the doctor who discharges him or her from the hospital says it is OK. This will be when your child is no longer jaundiced or vomiting.
  • A child who scratches, bites or “gets into fights, has an overall skin condition, or a bleeding problem should probably not attend child care while he or she has hepatitis. Your childs doctor can help you make this decision.

If you have any questions, be sure to ask your childs doctor or nurse.

How To Prevent Hepatitis B

Hepatitis B is a liver infection caused by a virus . It can be serious and theres no cure, but the good news is its easy to prevent. You can protect yourself by getting the hepatitis B vaccine and having safer sex. If you have oral, anal, and vaginal sex, use condoms and dental dams to help stop the spread of hepatitis B and other STDs.

Can Hepatitis B Be Prevented

Hepatitis E: Causes, symptoms, and treatment

The hepatitis B vaccine is one of the best ways to control the disease. It is safe, effective and widely available. More than one billion doses of the vaccine have been administered globally since 1982. The World Health Organization says the vaccine is 98-100% effective in guarding against the virus. Newborns should be vaccinated.

The disease has also been more widely prevented thanks to:

  • Widespread global adoption of safe blood-handling practices. WHO says 97% of the blood donated around the world is now screened for HBV and other diseases.
  • Safer blood injection practices, using clean needles.
  • Safe-sex practices.

You can help prevent hepatitis B infections by:

  • Practicing safe sex .
  • Never sharing personal care items like toothbrushes or razors.
  • Getting tattoos or piercings only at shops that employ safe hygiene practices.
  • Not sharing needles to use drugs.
  • Asking your healthcare provider for blood tests to determine if you have HBV or if you are immune.

Is Hepatitis Testing Recommended For People With Hiv

Yes. Everyone living with HIV should be tested for HBV and HCV when they are first diagnosed with HIV and begin treatment. People living with HIV who have ongoing risk factors for getting hepatitis B or hepatitis C should be tested annually.

In addition, new HCV screening recommendations from the Centers for Disease Control and Prevention call for:

  • One-time screening for all adults 18 years and older
  • Screening of all pregnant women during every pregnancy
  • Testing for all persons with risk factors, with testing continued periodic testing those with ongoing risk.

Symptoms Of Hepatitis B

Many people with hepatitis B will not experience any symptoms and may fight off the virus without realising they had it.

If symptoms do develop, they tend to happen 2 or 3 months after exposure to the hepatitis B virus.

Symptoms of hepatitis B include:

  • flu-like symptoms, including tiredness, a fever, and general aches and pains
  • loss of appetite
  • tummy pain
  • yellowing of the skin and eyes

These symptoms will usually pass within 1 to 3 months , although occasionally the infection can last for 6 months or more .

What Occupations Have Increased Risk Of Hepatitis B

In general, occupational groups with increased risk include:

  • Health-care workers repeatedly exposed to blood or blood products or those who are at risk of needlestick injury.
  • Pathologists, laboratory personnel, or embalmers.
  • Dentists, dental assistants, and dental hygienists.
  • Certain staff members of institutions for the developmentally handicapped.
  • Staff of institutions where workers may be exposed to aggressive, biting residents.

Travellers to regions with intermediate or high rates of endemic HBV infection may also consider being vaccinated.

Who Is Most Affected

Hepatitis B Virus

In the United States, rates of new HBV infections are highest among adults aged 40-49 years, reflecting low hepatitis B vaccination coverage among adults at risk. The most common risk factor among people with new HBV infections is injecting drugs, related to the opioid crisis.

The highest rates of chronic hepatitis B infection in the United States occur among foreign-born individuals, especially people born in Asia, the Pacific Islands, and Africa. Approximately 70% of cases in the United States are among people who were born outside of the United States. CDC developed this map of the geographic distribution of hepatitis B around the world – PDF. Other groups who have higher rates of chronic HBV infection include people who inject drugs and men who have sex with men.

Chronic Hepatitis B Infection

If you develop chronic hepatitis B, youll be given treatment to reduce the risk of permanent liver damage and liver cancer. Treatment does not cure chronic hepatitis B and most people who start treatment need to continue for life.

Without treatment, chronic hepatitis B can cause scarring of the liver , which can cause the liver to stop working properly.

A small number of people with cirrhosis develop liver cancer, and these complications can lead to death. Other than a liver transplant, there is no cure for cirrhosis. However, treatments can help relieve some of the symptoms.

How Is Hepatitis B Transmitted

Hepatitis B is spread in several distinct ways: sexual contact sharing needles, syringes, or other drug-injection equipment or from mother-to-child at birth.

In the United States, in 2018, injection drug use was the most common risk factor reported among people with an acute HBV infection, followed by having multiple sex partners. Less commonly reported risk factors included accidental needle sticks, surgery, transfusions, and household contact with a person with HBV infection. In the United States, healthcare-related transmission of HBV is rare.

Mother-to-child transmission of HBV is especially concerning, because it is preventable. An estimated 25,000 infants are born to mothers diagnosed with HBV each year in the United States, and approximately 1,000 mothers transmit HBV to their infants. Without appropriate medical care and vaccinations, 90% of HBV-infected newborns will develop chronic infection, remaining infected throughout their lives. Up to 25% of people infected at birth will die prematurely of HBV-related causes. For this reason, the standard of care for pregnant women includes an HBV test during each pregnancy so that the appropriate steps can be taken to prevent HBV-positive mothers from transmitting the disease to her infant.

Causes Of Hepatitis B

Hepatitis B is spread through contact with blood that contains the hepatitis B virus. If infected blood or body fluids enter another persons bloodstream, that person may become infected.

The time from exposure to the hepatitis B virus to the appearance of the illness is 45 to 180 days.

Risky activities that can cause infection include:

  • Sharing unsterile or unclean equipment for injecting drugs.
  • Piercing the skin with equipment that is not properly cleaned, disinfected and sterilised.
  • Sharing razor blades or toothbrushes.
  • Coming into contact with infected blood through open cuts or the mucous membranes of another person.
  • Having unprotected sex , especially if there is blood present.

Mothers who have hepatitis B can pass the virus to their babies or children at the time of birth or after birth. If the newborn baby is quickly immunised with 2 vaccines, they can be protected from getting hepatitis B.

All blood and blood products produced for medical purposes in Australia are carefully screened for hepatitis B and other blood-borne viruses. The risk of getting infected with hepatitis B from a blood transfusion is extremely low .

What Should You Know About Hepatitis B Before You Travel

Hepatitis B Home Treatment: Tips to Help You Feel Better

Hepatitis B is quite common in China and other Asian countries, where as many as 1 in 12 people have the virus, though many dont know it. Before traveling to those places, you should make sure youve been vaccinated against the virus.

In addition to getting the vaccine, you can take these additional precautions to reduce your risk of contracting the virus:

  • Refrain from taking illegal drugs.
  • Always use latex or polyurethane condoms during sex.
  • Make sure new, sterile needles are used during all piercings, tattoos and acupuncture sessions.
  • Avoid direct contact with blood and bodily fluids.
  • Know the HBV status of all your sexual partners.
  • Ask your doctor about possible vaccination before you travel to a place where hepatitis B is common.

A note from Cleveland Clinic

Hepatitis B is a liver disease that can cause serious damage to your health. One reason that is dangerous is that it can easily go undetected for years while damaging your liver. Talk with your healthcare provider about being tested for hepatitis B if you have any reason to believe that you were not vaccinated or if you have engaged in risky behavior. If you do test positive, follow the directions from your healthcare provider so that you can live a longer, healthier and happier life.

Prevent Infection After Contact With The Virus

If you think you have been in contact with the hepatitis B virus, see your doctor right away. Doctors typically recommend a dose of the hepatitis B vaccine to prevent infection. In some cases, doctors may also recommend a medicine called hepatitis B immune globulin to help prevent infection. You must get the vaccine dose and, if needed, HBIG shortly after coming into contact with the virus, preferably within 24 hours.

Vaccination And Other Prevention Measures

Vaccination is a safe and effective way of preventing the spread of hepatitis B. Since 1985, the hepatitis B vaccine has been part of the national immunisation schedule. In 1988, New Zealand was one of the first countries to introduce universal infant hepatitis B immunisation.The vaccine is given to babies at age six weeks, three months, and five months. Babies born to mothers with hepatitis B receive an extra dose of the vaccine at birth as well as a dose of hepatitis B-specific immune globulin.In children and adolescents who did not receive the hepatitis B vaccine in the first year of life, the full three-dose course is recommended.Hepatitis B immunisation is recommended and publicly funded for all infants and children up to their 18th birthday, household and sexual contacts of people with acute or chronic hepatitis B, and certain other high-risk populations. Measures that can help prevent the spread of the hepatitis B virus include:

  • Teaching children not to touch the blood or wounds of others
  • Covering cuts, scratches, and grazes
  • Not sharing personal items such as razors and toothbrushes
  • Never sharing needles or syringes if you use intravenous drugs
  • Practising safe sex, including the use of condoms
  • Seek assurance that body piercing and tattooing needles and equipment are sterile.

What Causes Hepatitis B

The hepatitis B virus causes hepatitis B. The hepatitis B virus spreads through contact with an infected persons blood, semen, or other body fluids. Contact can occur by

  • being born to a mother with hepatitis B
  • having unprotected sex with an infected person
  • sharing drug needles or other drug materials with an infected person
  • getting an accidental stick with a needle that was used on an infected person
  • being tattooed or pierced with tools that were used on an infected person and werent properly sterilized, or cleaned in a way that destroys all viruses and other microbes
  • having contact with the blood or open sores of an infected person
  • using an infected persons razor, toothbrush, or nail clippers

You cant get hepatitis B from

  • being coughed on or sneezed on by an infected person

  • eating food that is unclean or has not been properly cooked
  • hugging an infected person
  • shaking hands or holding hands with an infected person
  • sharing spoons, forks, and other eating utensils
  • sitting next to an infected person

Mothers who have hepatitis B can safely breastfeed their babies. If a baby receives hepatitis B immune globulin and starts receiving the hepatitis B vaccine to prevent hepatitis B infection shortly after birth, hepatitis B is unlikely to spread from mother to child through breastfeeding.15

How Do You Test For Hepatitis B

Can an asymptomatic person spread Hepatitis B? | Apollo Hospitals

A simple blood test carried out by a healthcare professional will show whether you have the virus. You may also be given extra tests to see if your liver is damaged.

If youve got hepatitis B you should be tested for other STIs. Its important that you tell your recent sexual partner/s so they can also get tested and treated. Many people who have hepatitis B dont notice anything wrong, and by telling them you can help to stop the virus being passed on. This can also stop you from getting the infection again.

Who Is More Likely To Get Hepatitis B

People are more likely to get hepatitis B if they are born to a mother who has hepatitis B. The virus can spread from mother to child during birth. For this reason, people are more likely to have hepatitis B if they

  • were born in a part of the world where 2 percent or more of the population has hepatitis B infection
  • were born in the United States, didnt receive the hepatitis B vaccine as an infant, and have parents who were born in an area where 8 percent or more of the population had hepatitis B infection

People are also more likely to have hepatitis B if they

  • are infected with HIV, because hepatitis B and HIV spread in similar ways
  • have lived with or had sex with someone who has hepatitis B
  • have had more than one sex partner in the last 6 months or have a history of sexually transmitted disease
  • are men who have sex with men
  • are injection drug users
  • work in a profession, such as health care, in which they have contact with blood, needles, or body fluids at work
  • live or work in a care facility for people with developmental disabilities
  • have been on kidney dialysis
  • live or work in a prison
  • had a blood transfusion or organ transplant before the mid-1980s

In the United States, hepatitis B spreads among adults mainly through contact with infected blood through the skin, such as during injection drug use, and through sexual contact.12

What Is Involved In A Liver Transplant

Hepatitis B virus information

A liver transplant is considered necessary when the liver is damaged and cannot function or in some cases of liver cancer. Your liver is very important. It is responsible for many functions related to making sure that your body stays healthy and is able to digest foods.

You may be eligible for a transplant if you have chronic hepatitis B infection or some of the diseases that may result from it, including liver cancer and cirrhosis. You will have to complete testing and be evaluated before being approved for a transplant. It is likely that you will be placed on a waiting list while an appropriate organ is found.

Donated livers come from two types of donors: living and deceased. Because the liver can regenerate, it is possible to use part of a liver for transplant. The remaining sections in both the donor and the receiver will grow into livers of adequate size.

People who get liver transplants must take anti-rejection drugs for the rest of their lives. These drugs make you more susceptible to infection. However, liver transplants have become more successful over time and continue to improve.
